US Active Shooter Incidents 2000-13 | a new study

The FBI has concluded a study of the 160 active shooter incidents in the US from 2000 - 2013. An active shooter incident is a situation in which a person (or, rarely, persons) actively engages in killing or attempting to kill people in populated locations like businesses, schools, government facilities, houses of worship, and open spaces.*

Among the principle findings:
  • Active shooter incidents increased in frequency. There were on average 6.4 incidents per year in 2000 - 2006, rising to an average of 16.4 incidents in 2007 - 2013.
  • There were 1,043 casualties (486 killed, 557 wounded—excluding the shooters).
  • Six of the 160 incidents involved a female shooter.
  • 158 of 160 incidents involved just one shooter.
  • 64 incidents fall within the federal definition of mass killing—three or more killed in a single incident
  • 107 incidents ended before police arrived
    • 90 shootings ended on the shooter’s initiative by suicide or flight. 
    • 21 incidents ended after unarmed citizens restrained the shooter.
    • Four incidents were interrupted by armed security guards or off-duty law officers. 
    • One incident was ended by a citizen with a valid firearm carry permit.
  • In the 64 incidents where duration could be determined, 44 ended in five minutes or less, 23 of those in two minutes or less.
  • In 21 of the 45 incidents where law enforcement engaged the shooter, nine officers were killed and 28 were wounded.
  • Active shooter incidents occurred in seven environments
    • 73 incidents occurred in commercial environments
    • 39 took place in educational environments
    • 16 were in government facilities
    • 15 were in open spaces
    • seven in residences
    • six in houses of worship
    • four in health care facilities.
* Active shooter incidents are distinguished from "ordinary" murders by the active and public nature of the crime
